Answer:
c. it involves a series of steps, each of which generates a reactive intermediate that brings about the next step
Explanation:
A chain reaction consist of many repeating steps. Chain reaction will never stop until all the reactant has been exhausted. It is more of a cycle of reaction that generate a reactive intermediate that brings about the next step.
Example of a chain reaction is the chlorination of methane.
CH4 + Cl2 ↔ CH3Cl + HCl
CH3Cl + Cl2 ↔ CH2Cl2 + HCl
CH2Cl2 + Cl2 ↔ CHCl3 + HCl
CHCl3 + Cl2 ↔ CCl4 + HCl
Homogeneous:
denoting a process involving substances in the same phase (solid, liquid, or gaseous).
Herogeneous:
of or denoting a process involving substances in different phases (solid, liquid, or gaseous).
(NH₄)₂CO₃ → 2NH₄⁺ + CO₃²⁻

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
